11 High-Protein Snack Ideas, Straight From Dietitians

You'll never have to dread that midday slump again whenever there's canned tuna tucked into your lunch bag, says registered dietitian Valerie Agyeman, RD. Why? "Tuna is flavorful, versatile, and nutrient-dense with vitamin D and heart-healthy omega-3s," Agyeman says. In one 2.6-ounce pouch, you'll get around 17 grams of protein, making it a super high-protein snack. Plus, you can easily pair it with mini wraps, fruit, or crackers for a filling snack, Agyeman says.
